If it's not visible here /EPiServer/Find/#manage/optimization/autocomplete I think you need to to something like:
Clear statistics and change the code and...
Another option could be to put your own proxy'ing code on top of Find's autocomplete-URL and filter the JSON yourself. I've done this to re-format to what the front-end code needed.
In my experience autocomplete in this manor is not helping the visitor and is open for abuse so I usually recommend some kind of search-as-you-type returning wildcard matches from some specific types or an editorial phrase repository.
I agree with you Johan, it is mutch better to have it working like for example www.prisjakt.se.
Thanks for the input, I will check out how I can filter away the noise
We are having strange suggestions in autocomplete. If someone for example have done a search for Alloy' they will get a result because Find will filter away the ' character but later it will return Alloy' as a suggestion for autocomplete.
Does anyone know if it is possible to filter this suggestions so we wont see them?
